Doomed Traveler

Two bodies for one mana, sequenced rather than stacked. The 1/1 is fodder, but killing it does not net your opponent a card so much as upgrade your board: the 1/1 Spirit that arrives flies, which means the removal spell or chump block that answered the Human Soldier hands you a better creature in exchange. That delayed value is the design idea. Sacrifice-matters decks read this as two triggers in one card, an aristocrats engine's favorite kind of fuel: feed the first body to a sacrifice outlet, get the Spirit, feed the Spirit too. Token-count and "creatures died this turn" strategies see the same doubling. The friction is that nothing happens until the first body dies, so the card is a setup piece, not a threat; it asks the deck around it to convert death into advantage rather than supplying advantage on its own. The structural ancestor is the chump blocker that refuses to stay dead, and this design renders that pattern about as plainly as a single white pip can: pay one, accept a creature that promises a flier the moment the ground body is spent.
